Hello:
Does Python support a peek like method for its file objects?
I'd like to be able to look at the next byte in a disk file before
deciding whether I should read it with, say, the read() method.
Is it possible to do so in Python?
Your answer would be much appreciated.
Thanks.
Ok, I finally got it working! See below

Hi,

I want to access IMAP folder with a web-browser.
Google shows me some dead projects. Most webmail applications
